Electronic temperature controller

一、 Technical Data
1. Working voltage：22VAC±10%，50/60Hz
2. Power consumption：﹤1W
3. Load electric current：﹤3A
4. Range of temperature control：10.0～35.0°C
5. Precision of temperature control：±1°C
6. Outer dimension:86mm×86mm×12mm(Height×Width×Thickness)
7. Speed of wind：four working status(High level, medium level, low level and automatic level)
二、 Performance & Characteristic
1. Indoor temperature accurate indication（resolving power is 1°C each）。
When indoor temperature is lower than 10。0°C or higher than 35。9°C，temperature indication is 10。0°C or 35。9°C。
2. Automatically switch on or off in eight hours.
3. Four adjusting modes for speed of wind.
4. It can be connected with three-coiled electric valves (two or three connection), electromagnetic valves or wind valves.
5. Switch of Mode: Cold air or warm air.
6. Control is made by microcomputer chip which is reliable in performance and fine in function.
7. LCD big screen, with operation interface like home appliances、easy operation and nice-looking in appearance.
8. Super thin and micro miniature design.
9. Nice function against dew: after shut off, the controller will continue to run another 30 seconds at low speed of fan.
三、 Operation methods
1. Switch controller
Use the key of"①"on the panel。 By this key, switch can be turned on or off 。When initiating the system, the controller is in "off" mode.

2. Adjust controller to monitor temperature
Use the key of"+"and"-"on the panel.
The key"+"is for increasing temperature. The range of adjustment is from the set temperature to 35.0°C with increasing 1°C at each time.
The key"-"is for decreasing temperature. The range of adjustment is from the set temperature to 10.0°C with decreasing 1°C at each time.
When initiating the system, the controller displays the indoor temperature interface，pre-set temperature is 24.0°C。
Press the above two keys, the controller display will be switched to set temperature interface. When setting is done, after 3 seconds, it will be switched to indoor display interface.
If the machine is turned on at the preset time, you are able to activate all these two keys.
3. Adjust the wind speed at fan and pipe
Use the key of"﹡" on the panel. Each time when pressing once, it will display the status of fan speed in the following order：

Automatic wind status:：According to indoor temperature and set temperature，intelligent rough control is adopted.
4. Adjust the set time and cancel time setting.
Use the key of "①" on the panel。
Range of setting is between one hour to eight hours，each setting interval is one hour. The initial setting starts from one hour。At the status of "On" mode, the function of "off" is available and where as at the status of "Off" mode, the function of "on" is available. When the time setting displays eight hours, press that key, time setting will be cancelled. The status for shutting off is small, so the time set is the time for starting the machine
5. Mode change between cold air and warm cold
At the bottom right corner, there is a manual switch that is for selection of operation mode.
4..Conditions for normal working and installation.（This product can work reliably under the below conditions）
1. Environment temperature：-5°C～+40°C.
2. Altitude height: The location for installing this product should not exceed the altitude height of 1000m.
3. Relative humidity for atmosphere: The average relative humidity for the wettest month should not exceed 90% per month.
五.Installation instruction (The operation should be carried out when the machine is turned off, otherwise the system will be dead very easily or the internal circuit will be damaged.
